PEPE CLAMP AND CONNECTION.

Application filed February 107 1922. Serial Nc. 535,626.

IVhile the uses of my device are more or less wide sp1-ea d. the saine is designed more especially for use in connection with self sinking piles, which are oftentimes sunk to such a depth that it is practically impossible to get at the hose connection so to release the same. ljlhile this is particularly true in cases where the pile is sunk in the bed of a stream where the top may be several feet below the surface. it may also occur in softv sandy structures where it is desired to sink an anchor some distance below the Surface 0f the sand. Among the objects of my invention, therefore, are to provide. a readily disconnectible pipe connection suitable for work of the character stat-ed` such that one `section 0f the pipe can he disconnected from the other by means of a longi` tudinal pull; to provide an improved clamp by means of which a pipe may be suspended andhandled and which can be detached from the pipe from a distance in a simple manner: to provide an improved clamp, the parts of which can be readily separated by means of a pull longitudinally of the pipe to which the clamp is connected: and such further objects, advantages and capabilities as will later more fully appear. f

My invention further resides in the combi-- nation, construction and arrangement of parts illustrated in the accompanying drawings, and while I have shown therein a preferred embodiment` I desire the same to be understood as illustrative only and not as limiting my invention.

In the drawings annexed hereto and forming a part hereof,

Fig. 1 shows a broken elevation of the upper portion of a self sinking pile, together with the upper end of the fluid supply pipe thereof and the pipe connected thereto for leading water into the pile from an external source of supply.

Fig. 2 is a fragmentary longitudinal sec` tion of such a construction.

Fig. 3 is a horizontal sectional plan substantially along the plane indicated by the line 3-3 Fig. 2.

Fig. 4 isa broken plan view of the clamp shown in the other iigures, with the locking keys omitted.

Fig. 5 isan elevation of the construction shown in Fig. 4.-.

Referring more in detail to the annexed drawings, numeral l designates the outer or cured in opposite ends of one ofthe meml bers, as 4i, or oneis secured in one end of each of these members el. and 5, the looped portion extending through a suitable slot in the eo-operating end of the other member. As shown in the present drawings,` these slots 7 are both in member 5, but it will be understood that one of the members 6 may be mounted in member at while the other one is mounted in the opposite end of member 5.

These looped members (i are adapted to be fastened in place by means of keys 8, each provided in vone end with an aperture A9, to which may be secured a flexible member by means of which keys 8 may be withdrawn .from a distance by a longitudinal pull on the flexible member. A short fiexible member may also connect keys S with eyes or the like 8, so Athat they will not become misplaced or lost and will at all times be handy for use. pile has been sunk to a depth below the water surface orjland surface, so that the clamp is inaccessible, or. if for any'other reason, this be true, it will be easy. by pulling on the iiexible members, to withdraw the-keys from the openings inthe members 6. Then this has been done members el. and 5 will readily separate and swing` away from beneath the flange-like member 3. thus permitting the mechanism by means of which the piles are handled to be withdrawn without difficulty. To cooperate in permitting this to be done the pipe 11 is connected to the pipe 2 by means of such a connection that the one can be separated from the other by a longitudinal pull thereon. As shown in the present drawings, this is accomplished by securing an internally and externally threaded ring l2 to the lower end of pipe 11 and securing to this ring a sleeve 13. the opposite end of which is provided with a ring 14e. internally bevelled as shown at l5, so that a rubber or similar ring 16 may be inserted to form a tight joint between the parts as shown. This connection forms a It will therefore be seen that if the joint between sleeve 13 and pipe 2 sufficiently tight so that there is substantially no leal'rage between these parts when the water 1s being forced through the piping to cause the pile to sink.

As .shown in the drawings, means, in the form of eye-bolts 18, securedin members 4' and 5 so that flexible means, such as chains, may be secured thereto for the handling of the piles.

It is of course understood-that the specific description of structure set forth above may be departed from without departing from the spirit of my invention as set forth in this specification and the appended claims.

Having now described my invention, I claim l. Means for raising' and lowering a pipe, including a separable clamp, one vof the parts thereof having U-bolts extending transversely of the ends thereof, the other part having slots therein through which the bend of the U may slide and beyond which it may project, locking keys adapted to .slide through the projecting bend of the Ubolts, and means for pulling longitudinally on the keys to withdraw them from locking position.

2. A pipe clamp of the character described comprising a pair of complementary pipe engaging members provided at their respective ends with cooperating extensions, perforated for the reception of means to hold the members together around a pipe, means secured in one of said perforated ends and provided with a vertically opening looped portion to be slipped through the perforated end ofthe cooperating pipe engaging member, and means to be longitudinally slipped vertically through the looped portion to hold the parts in cooperative relation or to permit them to be separated.

3. A pipe clamp of the character described comprising a pair of complementary pipe engaging members provided at their respective ends with cooperating extensions, perforated for the reception of means to hold the members together around a pipe, means secured in one of each pair of said cooperating perforated ends and each provided with a vertically opening looped portion to be slipped through the perforated end of the cooperating pipe engaging member, means to be passed longitudinally into the looped portions to hold the parts in cooperative relation or to be pulled out to ypermit them to be separated, and means connected to said last named means for Withdrawing them from a distant position.

4.. A structure of the character described coi'nprising a pair of complementary curved members adapted to engage and substantially surround a pipe, said members each being provided with a perforated projection, supporting means passing through said perfor-ations whereby the supported' structure may be raised or lowered, means mounted in the opposite ends of one of'saidcurved members and each adapted to' extend through a perforation in the other member, and means adapted to pass through said last named means to hold the curved'members together or to be withdrawn*therefrom by being pulled lengthwise in the vdirection of the length of the supported pipe.

5. A structure of the character described comprising a pair of members curved to'eooperate in the supporting of a' pipe or similarly shaped structure, means for sustaining, raising andlowering said members, looped members each secured in one of saidv first named members and slidable through a perforation. in the cooperating member tey release the members from each other, locking pins slidable through said looped members, and means attached to said pins for withdrawing them fromv a distance.

In witness whereof, I hereunto subscribe my name to this specification.y
